A statistical analysis on the removal of organic matter in subsurface flow constructed wetlands in the U.K.
The performances of 98 subsurface flow constructed wetlands in the U.K. are analysed for the rates of organic matter removal from various wastewaters. The analyses of 78 subsurface horizontal flow wetlands are focused on deriving the value of rate constant K(BOD) in the Kickuth equation and evaluating the probability of meeting the target when the equation is used in design. The analyses of 20 vertical flow wetlands are focused on establishing the correlations between BOD (biochemical oxygen demand) removal rate and organic loading; an empirical relation has been developed to estimate the surface areas of the wetlands.
